+# Supertron2-Reranker-8B
+
+Supertron2-Reranker-8B is a short fine-tune of `Qwen/Qwen3-VL-Reranker-8B` for text reranking.
+
+It is trained on real reranking pairs, primarily MS MARCO, for search and RAG reranking.
+
+## Usage
+
+```python
+import torch
+from transformers import AutoModelForImageTextToText, AutoProcessor
+
+model_id = "Surpem/Supertron2-Reranker-8B"
+processor = AutoProcessor.from_pretrained(model_id)
+model = AutoModelForImageTextToText.from_pretrained(
+    model_id,
+    torch_dtype=torch.bfloat16,
+    device_map="auto",
+)
+
+query = "What is the capital of France?"
+documents = ["Paris is the capital of France.", "Mars is the red planet."]
+prompts = [
+    f"Retrieve text relevant to the user's query.
+Query: {query}
+
+"
+    f"Document: {document}
+
+"
+    "Is this document relevant to the query? Answer yes or no:"
+    for document in documents
+]
+inputs = processor(text=prompts, padding=True, return_tensors="pt").to(model.device)
+yes_id = processor.tokenizer.encode("yes", add_special_tokens=False)[-1]
+no_id = processor.tokenizer.encode("no", add_special_tokens=False)[-1]
+
+with torch.inference_mode():
+    logits = model(**inputs, return_dict=True, logits_to_keep=1).logits[:, -1, :]
+scores = (logits[:, yes_id] - logits[:, no_id]).float()
+print(scores)
+```
+
+## Limitations
+
+This is a short 30-minute H100 fine-tune. It should be evaluated on your retrieval domain before production use.
